[UNITED STA-Tes ioFEi'cfiE f ORVILLE MITCHELLIOF DAVLLASrTEXVAS METAL Fiiiiniiici'RomainA Application filed Novembery This invention relates to a novel construction of feeding roller adapted to be used in pairs for withdrawing cotton from hoppers` rality of casing sections which may be readily formed or shaped with dies, thereby enabling the rollerto be rapidly produced, and at a greatly Areducedr cost as compared with the present type offeeding rollers.

With the above and other objects in view, the invention consists of an all-metal feeding roller star-shaped in cross-section and comprising-a plurality` of longitudinal casing sections, each of which is provided with a point or flute, said sections being mounted on starshaped spiders havingalternate short points, the flutes of the casing sections beingiitted over the longer points of the star-shaped spiders and the side members of'adjacent casing sections being fitted against opposite sides of the corresponding shorter' points of the spiders and united beyond said points to yform points of the star-shaped roller alternating with the flutes thereofand of the same radial-` length.

Amount-ing l'casing --sections 18, {Fig} 5,' onzth 95 the result is that vthe peripheral 'edges of the. y-star-shapedspiders and uniting theedgepor- As shown by Figs. 3 and 5 each of the casing sections 8 is constructed from a single sheet of metal which is formed by dies into the shape in cross-section shown in Fig. 5. That is to say, each of the casing sections is provided with a central, longitudinal flute 10, designed to form one of the blades of the roller, and with upwardly inclined, oppositely directed side members 11, cach of which is again bent slightly' at an angle at its edge portion, as indicated at 12. The angular portions 12, are provided at intervals with apertures 13 to receive rivets 9, in case this manner of securing the casing sections together is employed. It will be understood however, that the casing sections could be connected together by welding or in any other 'desired way. f y

v n the case of spiders being employed having six points, as illustrated in the drawings, three casing sections 8 are used to :form the shell of the roller. The flutel 10 of each of these casing sections is of a size and 4shape to fit snugly overcorresponding points dof the two spiders 5, and when so positioned the side members 11 will rest against the sides'of the shorter points 7, with the angular portions rivets 9, by welding, or in any other preferred 12 projecting beyond the outer extremities of these points and in contact. The angular portions 12 of adjacent casing sections are then secured together, as previously explained, by

InpFigs. 1, 2` and 4, I have indicated the spiders 5 as being fixedly secured' on shaft 2 by means of keys 14. Any other desirable way of securing the spiders on they sh aft could lhowever be employed.
